I set up this macro:
#showtooltip
/equipslot 13 Gnomish Battle Chicken
/use Gnomish Battle Chicken
/equipslot 13 Mindtap Talisman
I have seen it pull stealthies out multiple times. Switching to another on-use trinket triggers a cooldown, but switching to something like mindtap talisman that is just a stat stick works perfect.
I want to clarify that I don't seem to get the speed attack buff, but it is nice to just have the additional damage to start a fight and potentially find a stealthy. Long cooldown though.

EDIT: I tested the damage in a duel, and the battle chicken does basically 0 damage. Probably a lot more trouble than its worth messing with this thing once I realized that.
